SOLUTION: Arm parts 5a of a pair of arm rest members 5 are pivoted near both end parts of rotatable rod members 4 arranged on the back of a back rest part 2 while being linked through link rods 7. At the same time, the pair of arm rest members is positioned behind the back rest part while being housed. The pair of arm rest members can be arranged at the roughly vertical position of keeping it housed as located behind the back rest part and at the roughly horizontal position that allows resting of arms. |
